GABRIEL A. BOBRICK, OF NEWY YORK, N. Y.

NURSING-BOTTLE.

SPECIFICATION forming part of Letters Patent No. 468,759, dated February9, 1892. Application filed June 1'7, 1891. Serial No. 396,573. (Nomodel.)

To all whom it may concern.-

Be it known that I, GABRIEL A. BOBRICK, of New York city, in the countyand State of New York, have invented a new and Improved Nursing-Bottleand Nipple, of which the following is a full, clear, and exactdescription.

In the construction of nursing-bottles and nipples it is necessary toprovide for the easy removal of the nipple, so that the bottle may beeasily filled or cleaned, and a dimcult-y arising from this constructionis that the nip plc is liable to accidental displacement.

The object of my invention is to produce a bottle and nipple which maybe quickly and easily secured together or separated and which will notinterfere with the interior construction of the bottle but will permitit to be filled or cleaned as easily as bottles of the common form maybe similarly operated on.

To this end my invention consists in certain features of constructionand combinations of parts which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of referenceindioatecorresponding parts in all the views.

Figure 1 is a side elevation, partly in section, of a bottle and nippleembodying my invention. Fig. 2 is a broken detail sectional view showinga modified form of the nipple, and Fig. 3 is a broken detail sectionalView showing another modification of the nipple.

The preferred construction is shown in Fig. 1, and in this case thebottle 10 is shaped like a common bottle, but is provided on oppositesides of its neck with projecting lugs 11, which are preferably arrangedso as to have a downward inclination. The nipple 12 is usually of rubberand is adapted to slip upon the neck of the bottle, and near the lowerend of the nipple and on opposite sides are perforations which areadapted to receive the lugs 11, and to prevent the nipple from beingunduly strained it is reinforced around the perforations, as shown at 18in all the figures. It will thus be seen that the nipple may be easilyslipped to its seat on the bottle and that the lugs, projecting as theydo through the nipple, make accidental displacementimpossible.

In Fig. 2 the bottle has the lugs described above, and the nipple 14 isprovided with holes to fit the lugs; but the nipple is also providedwith a ring'15 at its upper end, through which a rubber tube 16 may bepassed and coupled to a glass tube 17, which may project into the bottlein the usual way. The rubber and glass tubes form no part of myinvention, and the nipple is shown in connection with the tubes toillustrate its adaptability to the common forms of bottles and theirattachments.

As shown in Fig. 3, the bottle has the lugs described above, and thenipple 18 differs essentially in form but not in principle from thenipples described above. The nipple 18 has projecting cars 19 uponopposite sides, which ears are thickened and perforated, so as toreceive the lugs, and the inner portion of the nipple is formed into apacking-ring 20, which fits closely around the glass stopper 21, adaptedto enter the neck of the bottle. This stopper has a central bore,through which the tube 16 may pass, and it is a modification of thedevice shown in Fig. 2.

The three views will illustrate the universal adaptability of myimproved nipple and lug to diiferent bottle attachments; and theinvention consists in the fastening, which is common to all the devicesshown.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent The combination, with a bottle havingprojecting lugs on its neck, of a nipple having perforations to receivethe lugs, substantially as specified.
